We do a study on distracted driving. Participants play a driving video game where the goal is to keep the car in the center of the lane. We record the number of times a wheel touches/crosses one of the lines as an error (so higher scores = worse driving). Two variables are manipulated. Subjects drive under different levels of distraction and encounter different levels of wind gusts. Each individual participant is exposed to all nine of the conditions - that is each person plays the game with no windo distraction, no wind/low distraction, etc. Results are below. Distraction Wind None Low High Means None 4 4 4 4 Low 12 12 9 High 20 20 15 Means 4 12 12 1. Label the design using our factorial design language (an earlier example was a "2x3 factorial with one between- and one within-factor" - that's the format I'm asking for). design name 2. Use the decision-making flowchart to discuss what comparisons we should make in the table. a) Is there an interaction? How do you know? interaction b) What comparisons should we make next? Be sure to explain/make your answer clear - don't just list a technical term. Comparison set 1 c) What happens next? For comparison set 1, which require further analysis? Which do not? Describe what further comparisons you would make. Comparison set 2
